# Runway Model Router 'no eligible model': raise max credits or enable more models

## TL;DR

[Official Runway API docs (troubleshooting)]: A Model Router 'no eligible model' error means no model satisfies the configuration constraints plus the request together, and the error identifies which constraint(s) emptied the pool. The typical culprit is max credits per generation combined with the requested duration leaving nothing eligible. Fix it in the Developer Portal by adjusting the router configuration: enable additional models or raise the max credits per generation (see Configuring a Model Router).

Use this when you run into the situation in the title.
